I hate to be the stick in the mud, but I have shot hammer 124's out of a creedmoor at 2900fps and didn't get an exit wound a slightly quartering mule deer at 224 yds. I have however had exit wounds on 10+ deer using the Sierra 130HPBT GameKing ranging from 45yds to 257yds. A monolithic bullet alone doesn't guarantee an exit wound. I will say that shot placement, twist/velocity etc will determine exit wounds.
6.5mm bullets that you would expect to exit but haven't for me. 160 Hornady RN, 124 Hammer, 140 Speer Gold Dot
6.5mm bullets that have always exited. 110 hammer, 130HPBT gameking, 130 gamechanger
